the air filter cover, and the filter base.

NOTE! The clutch has a left-hand thread, screw
clockwise to dismantle the clutch. The clutch is

stop using a striking tool results in
a risk of damage to the flywheel's
locking mechanism (keyway/key).

drum can be pulled off the axle.
Note the spacer sleeve located between the belt
pulley and crankcase.
